Scientists are closer to establishing a definitive bacterial cause for the skin condition rosacea. This will allow more targeted, effective treatments to be developed for sufferers, according to a review published in the Journal of Medical Microbiology.

Rosacea is a common dermatological condition that causes reddening and inflammation of the skin mostly around the cheeks, nose and chin. In severe cases skin lesions may form and lead to disfigurement. Rosacea affects around 3% of the population – usually fair-skinned females aged 30-50 and particularly those with weak immune systems. The condition is treated with a variety of antibiotics, even though there has never been a well-established bacterial cause.
